CombGaussLorentzKT

Description

A combined function of the Gaussian decay and Lorentz KuboToyabe decay.

\[A(t)=A_0\left(\frac13+\frac23\left(1-(\sigma t)^2-\lambda t\right)e^{-\frac{(\sigma t)^2}{2}-\lambda t}\right)\]

where,

\(\sigma\) is the KuboToyabe decay rate,

\(A_0\) is the amplitude,

and \(\lambda\) is exponential decay rate.
